ATLANTA -- A Georgia Tech graduate student shot another student who was trying to break into his off-campus house Tuesday morning, according to Atlanta police.

The incident happened at a house on Curran Street at around 5:30 a.m. Three Georgia Tech students were asleep inside the house when they awoke to the sound of glass breaking, Atlanta Police spokesman Capt. Adam Lee III said.

The students saw a man, now identified as 22-year-old Georgia Tech student Adam Keller, trying to enter their house through a broken window. One of the students grabbed a gun and shot Keller once in the chest, according to Lee.

Keller was under the influence and believed that he was trying to enter his own house, according to police. He also walked into another Curran Street home before arriving at the house where he was shot. David Beissner was alseep on the couch when he saw the shirtless student walk through his front door.

"By the time I got up the guy had already gone out the back door and across the street," Beissner said. "We basically saw him throw a stool through the window and then he climbed in and got shot."

Keller was rushed to Grady Memorial Hospital, where he is in stable but critical condition. He faces charges of property damage and criminal trespass, Jones said.

The three students inside the house were not hurt. Jones said they did not know Keller, and are not being charged.

Many living students in the Home Park neighborhood where the shooting took place said they're on edge, because three armed robberies took place there this past weekend.

"Georgia Tech students, we're not really known for being the toughest crowd," said student Greg Lennartz. "[Thieves] know we've got about $3000 worth of electronics in our bookbags, and we're not going to fight back."

Some students have decided they'll at least try, and have armed themselves with pepper spray. Atlanta and Georgia Tech police have stepped up patrols in the area.
